Jonathan Davis’s Science Experiment

HCI=Hydrochloric acid, H2SO4= Sulfuric Acid, Zn-Zinc, Cu=Copper, Sn=Tin, Pb= Lead, Fe=Iron

Reason of creation of experiment

Knew I had a few misconceptions on what happens when you bathed metals into Acids. I also just wanted to see what would happen to the metals or acids themselves.

Proposal/Plan

Get various metals and see what kinds of metal are available. Preferably in sheet or powdered form. Get 2-4 types of acids and put the same or approximant amounts of the metals in each of the test tubes which will be filled partially filled up with different acids. After a few weeks or days, depending on what happens. I will come back to my experiments and see how each of them has changed in shape, color, and maybe smell.

Materials

Iron Power/ Granules-used in 3 test tubes
Copper powder- used in 2 test tubes
Lead granules/powder- used in 3 test tubes
Tin granules- used in 1 test tube
Zinc granules- used in 3 test tubes

Sulfuric Acid-6M
10% Acetic Acid- Molar ?

12 test tubes
Test tube rack

Acid strength testing Machine

Results

external image clip_image002.jpg Results on all test tubes were completely different from what I had expected would have happened, particularly on the test tubes where the color of the acid would change into a very dark green or orange color. A few of the test tubes had had crystals growing inside of them and 2 of them had crusted over on the top. Pictures below show results…
